Based on DOM, two-stage work pattern of information extraction and the conception of page information unit has been proposed. PIU is extracted and classified by classified algorithm, and information is extracted in PIU. It is implemented finally that the key information of the online goods is extracted. A intelligent Comparison Shopping System based on Web Information Extraction is implemented with analysis and design about flow and frame structure. It is showed that the algorithm is steady and has higher Recall and Precision with the sample testing. Key words: Comparison-shopping, Information extraction, Intelligent business, Document object model
